Citrics are the best choice. They are versatile (day/night, formal/informal), refreshing, happy, sunny and manly: Eau Sauvage, Eau D'Hadrien, Armani Pour Homme, Bois de Cedrat, etc. etc.
Classic colognes such as Extra Vieille and Acqua di Parma are also very good.
Tropical fruits are a good choice for summer. Try Jardin sur Le Nil or Jardin en Mediterranee. But beware: fruits are very very informal. You cannot go to a formal event smelling like mango.
